Abstract
Endogenous endophthalmitis (EE) is an ocular infection resulting from hematogenous spread from the remote primary source. Risk factors include endocarditis, bacteria meningitis, immunosuppressive state, and invasive procedures in patients with sepsis. We present a case of a 43-year-old gentleman with poorly controlled diabetes mellitus who was admitted for bilateral nasoseptal cellulitis with a right nasal wall abscess and right vocal cord palsy. At presentation, he just had preseptal cellulitis without any posterior segment involvement. He underwent incision and drainage under the Otorhinolaryngology team. Unfortunately, postoperatively he developed sepsis with a hematogenous spread of infection systemically involving his right eye (endophthalmitis) and his heart valve (infective endocarditis). Blood culture revealed Methicillin Sensitive Staphylococcus Aureus (MSSA) infection. He had six weeks of intravenous cloxacillin and three times intravitreal injections of vancomycin and ceftazidime with complete resolution of signs and symptoms. In the case of a poorly controlled diabetic patient with an extensive regional infection, the presence of ocular symptoms and signs that are suggestive of EE must be taken seriously and warrant a complete eye examination as early detection and treatment of EE is crucial for better prognosis.

Abstract
Purpose: This work compares clinical presentation and course of bacterial and fungal causes of endogenous endophthalmitis (EE). Methods: A single-institutional study of consecutive patients diagnosed with EE was conducted at the University of Pittsburgh Medical Center between September 2015 and September 2018. Exclusion criteria included history of ocular trauma, intraocular surgery or injection 6 months before presentation, or primary external ocular infection. Data included demographics, medical and ocular history, clinical examination, culture data, therapeutic interventions, final corrected visual acuity (VA), and mortality. Results: Thirty-six eyes of 26 patients were diagnosed with EE during a 3-year period. Median age at diagnosis was 55.5 years (range, 19-86 years). Based on ocular and systemic cultures, 19 patients had bacterial EE and 6 patients had fungal EE; findings from all cultures remained negative in 1 patient. All patients had risk factors for EE. Presenting VA, subjective symptom report, and objective measures of intraocular inflammation were similar between bacterial and fungal causes. Overall, EE presented indolently and was initially misdiagnosed in 19% of cases. Complications including final VA less than 20/200, retinal detachment, enucleation, or death within 6 months of diagnosis were equivalent between bacterial and fungal cases. Conclusions: The presentation of EE is remarkably different from that of exogenous endophthalmitis. Without a high index of suspicion, the indolent presentation of EE may lead to misdiagnosis. No clinical features reliably differentiated bacterial and fungal sources. This highlights the importance of considering empiric therapy for antibacterial and antifungal coverage on initial presentation.

Abstract
Ocular microbial infection has emerged as a major public health crisis during the past two decades. A variety of causative agents can cause ocular microbial infections; which are characterized by persistent and destructive inflammation of the ocular tissue; progressive visual disturbance; and may result in loss of visual function in patients if early and effective treatments are not received. The conventional therapeutic approaches to treat vision impairment and blindness resulting from microbial infections involve antimicrobial therapy to eliminate the offending pathogens or in severe cases; by surgical methods and retinal prosthesis replacing of the infected area. In cases where there is concurrent inflammation, once infection is controlled, anti-inflammatory agents are indicated to reduce ocular damage from inflammation which ensues. Despite advances in medical research; progress in the control of ocular microbial infections remains slow. The varying level of ocular tissue recovery in individuals and the incomplete visual functional restoration indicate the chief limitations of current strategies. The development of a more extensive therapy is needed to help in healing to regain vision in patients. Stem cells are multipotent stromal cells that can give rise to a vast variety of cell types following proper differentiation protocol. Stem cell therapy shows promise in reducing inflammation and repairing tissue damage on the eye caused by microbial infections by its ability to modulate immune response and promote tissue regeneration. This article reviews a selected list of common infectious agents affecting the eye; which include fungi; viruses; parasites and bacteria with the aim of discussing the current antimicrobial treatments and the associated therapeutic challenges. We also provide recent updates of the advances in stem cells studies on sepsis therapy as a suggestion of optimum treatment regime for ocular microbial infections.

Abstract
BACKGROUND Endogenous endophthalmitis (EE) is a fulminant ocular disease. This study was conducted to explore frequent pathogens and significant prognostic factors associated with poor ocular outcomes. MATERIALS AND METHODS A retrospective analysis was performed in a tertiary hospital in Korea. Thirty-nine patients, treated between January 2000 and June 2017, were eligible for the analysis. Ocular outcomes were classified as follows: 1) no light perception (NLP), 2) light perception (LP), 3) hand motion (HM), 4) counting fingers (CF), and 5) 20/200 or better. Logistic regression and decision tree analyses were used to identify risk factors that were associated with poor outcomes. RESULTS Pathogens were identified in 23 (58.9%) samples from blood, liver aspirate, and/or vitreous humor. Klebsiella pneumoniae was the most frequent organism (12/39, 30.8%), followed by Candida species (3/39, 8.3%). The most common combined infection was liver abscess (16/39, 41.0%). Acute pyelonephritis occurred in 30.8% of cases (12/39). Final ocular outcomes were as follows: 35.9% (14/39) NLP, 15.4% (6/39) LP, 15.4% (6/39) HM, 7.7% (3/39) CF, and 25.6% (10/39) 20/200 or better. K. pneumoniae was a poor prognostic factor in univariate (odds ratio [OR], 13.3; 95% confidence interval [CI], 2.1-130.9) and multivariate (OR, 17.5; 95% CI, 2.1-398.8) regression analyses (NLP and LP vs. HM, CF, and 20/200 or better). Other factors did not reach statistical difference. Decision tree analysis identified K. pneumoniae as a node that divided ocular outcomes (P = 0.017). CONCLUSIONS In conclusion, K. pneumoniae is the most frequent causative pathogen of EE. Considering the poor prognosis and rapid progression of K. pneumoniae EE, physicians should test for K. pneumoniae EE in patients who experience acute systemic infections with ocular signs and symptoms.

Abstract
AimsTo identify the clinical features and prognostic factors of endogenous endophthalmitis caused by Klebsiella pneumoniae.MethodsThis is a retrospective case series of all patients with Klebsiella endophthalmitis managed from January 2006 to December 2015 by Kowloon East Ophthalmic Service. Statistical analysis involved hypothesis testing on the SPSS 18.0 software (SPSS). A significance level of P<0.05 was taken.ResultsIn the 10-year period, K. pneumoniae accounted for 19 out of 39 cases of endogenous endophthalmitis (48.7%). The mean age of patients was 67.9 years. Bilateral involvement occurred in five patients (26.3%). More than half of the patients (10/19, 52.6%) had underlying diabetes mellitus. Most patients had concurrent liver abscess (18/19, 94.74%). Ten patients (52.6%) had disseminated intravascular coagulopathy. Eight patients (42.1%) were in shock. The overall mortality was 21.1% (4/19). Septic shock was associated with a significantly higher mortality (50.0 vs 0%, P=0.018). Among the 15 survivors, nine patients (60.0%) required evisceration and three patients (20.0%) had no light perception in an involved eye. Eyes with diffuse posterior involvement were less likely to have a final visual acuity of logMAR 0.30 or better than those with focal posterior involvement (4.76 vs 100% 4.76%, P=0.002). Patients with hypopyon were more likely to require evisceration (85.71 vs 25.00%, P=0.02).ConclusionsKlebsiella endophthalmitis is associated with a high incidence of diabetes mellitus and liver abscess. Prognosis remains poor. Universal ocular screening and systemic control in patients with Klebsiella sepsis are recommended.

Abstract
Bacterial endophthalmitis is an infection and inflammation of the posterior segment of the eye which can result in significant loss of visual acuity. Even with prompt antibiotic, anti-inflammatory and surgical intervention, vision and even the eye itself may be lost. For the past century, experimental animal models have been used to examine various aspects of the pathogenesis and pathophysiology of bacterial endophthalmitis, to further the development of anti-inflammatory treatment strategies, and to evaluate the pharmacokinetics and efficacies of antibiotics. Experimental models allow independent control of many parameters of infection and facilitate systematic examination of infection outcomes. While no single animal model perfectly reproduces the human pathology of bacterial endophthalmitis, investigators have successfully used these models to understand the infectious process and the host response, and have provided new information regarding therapeutic options for the treatment of bacterial endophthalmitis. This review highlights experimental animal models of endophthalmitis and correlates this information with the clinical setting. The goal is to identify knowledge gaps that may be addressed in future experimental and clinical studies focused on improvements in the therapeutic preservation of vision during and after this disease.

Abstract
Endogenous endophthalmitis is an ophthalmic emergency that can have severe sight-threatening complications. It is often a diagnostic challenge because it can manifest at any age and is associated with a number of underlying predisposing factors. Microorganisms associated with this condition vary along a broad spectrum. Depending upon the severity of the disease, both medical and surgical interventions may be employed. Due to rarity of the disease, there are no guidelines in literature for optimal management of these patients. In this review, treatment guidelines based on clinical data and microorganism profile have been proposed.

Abstract
Purpose: The purpose of this study is to identify the possible factors for preserving the eyes after late or suboptimally treated endogenous endophthalmitis secondary to Klebsiella pneumoniae (KP) liver abscess. Methods: A retrospective chart review was conducted for patients admitted with KP liver abscess from January 1991 to June 2012. Results: Six hundred and ninety-three patients with KP liver abscess were recorded, in which endophthalmitis was identified in 53 cases (65 eyes, 8.29%). Diabetes was significantly associated with the development of endophthalmitis (p = 0.014). Eleven eyes received their last ocular treatment ≥10 days and final vision ≥ counting fingers, and were defined as benign type KP endophthalmitis. The absence of diabetes was the only consistent candidate factor for benign type KP endophthalmitis. Conclusion: A lack of ongoing diabetes is an important factor in preserving eyes with late or suboptimally treated endogenous endophthalmitis second to KP liver abscess.

Abstract
Bacterial endophthalmitis is endogenous in 2–6% of cases and is frequently misdiagnosed initially. Klebsiella pneumoniae is being increasingly recognised as an aggressive causative organism, and it is particularly prevalent in Asian populations. We describe the case of a 71-year-old female of Southeast Asian origin with type 2 diabetes mellitus who presented with visual loss secondary to bacterial endophthalmitis and concomitant cerebral abscesses. Imaging revealed the probable primary source of infection to be a liver abscess. She developed retinal detachment and subsequently underwent an evisceration of her right eye. A Klebsiella spp. was identified from the eye tissue by 16S rRNA amplification. Klebsiella pneumoniae endophthalmitis has a characteristic disease phenotype and a particularly aggressive course with poor visual outcomes observed in most cases. This case highlights the risks of metastatic infection including bacterial endophthalmitis in association with Klebsiella infection.

Abstract
We review a total of 342 cases of endogenous bacterial endophthalmitis reported between 1986 and 2012. Predisposing conditions were present in 60%, most commonly diabetes, intravenous drug use, and malignancy. The most common sources of infection were liver, lung, endocardium, urinary tract, and meninges. Systemic features such as fever were present in 74%, hypopyon in 35%, and an absent fundal view in 40%. Diagnostic delay occurred in 26%. Blood cultures were positive in 56%, and at least one intraocular sample was positive in 58% (comprising 26% anterior chamber samples, 59% vitreous taps, and 41% vitrectomy specimens). Worldwide, Gram negative infections (55%) were more frequent than Gram positive (45%) infections, particularly in Asia. Over the last decade, 11% of eyes were treated with systemic antibiotics alone, 10% intravitreal antibiotics alone, 36% systemic plus intravitreal antibiotics, and 20% systemic plus intravitreal antibiotics plus pars plana vitrectomy. The most commonly used intravitreal antibiotics were vancomycin (for Gram positive infection) and ceftazidime (Gram negative). The median final visual acuity was 20/100, with 44% worse than 20/200. Among all cases, 24% required evisceration or enucleation, and mortality was 4%. Both intravitreal dexamethasone and vitrectomy were each associated with a significantly greater chance of retaining 20/200 or better and significantly fewer eviscerations or enucleations-these warrant further study. For most patients, treatment should include a thorough systemic evaluation and prompt intravitreal and systemic antibiotics.

Abstract
PURPOSE/AIM Klebsiella pneumoniae causes a blinding infection called endogenous endophthalmitis. The role of innate immune recognition of K. pneumoniae in the eye during infection is not known. We hypothesized that intraocular recognition of K. pneumoniae was mediated by Toll-like receptor (TLR)-4 and may be dependent on MagA-regulated hypermucoviscosity. MATERIALS AND METHODS Experimental endophthalmitis was induced in C57BL/6J or TLR4(-/-) mice by intravitreal injection of 100 CFU of wild type or ΔmagA K. pneumoniae. Infection and inflammation were quantified by determining viable K. pneumoniae per eye, retinal responses via electroretinography, myeloperoxidase activity of infiltrating neutrophils and the proinflammatory cytokine and chemokine response. RESULTS C57BL/6J and TLR4(-/-) mice could not control intraocular wild-type K. pneumoniae growth. TLR4(-/-) mice were less able than C57BL/6J to control the intraocular growth of ΔmagA K. pneumoniae. Retinal function testing suggested that infection with ΔmagA K. pneumoniae resulted in less retinal function loss. There was a TLR4-dependent delay in initial neutrophil recruitment, regardless of the infecting organism. The proinflammatory cytokine/chemokine data supported these results. These findings were not due to an inability of TLR4(-/-) neutrophils to recognize or kill K. pneumoniae. CONCLUSIONS These studies suggest that TLR4 is important in the early intraocular recognition and host response to K. pneumoniae. However, the role of MagA in TLR4-mediated intraocular recognition and subsequent inflammation is less clear.

Abstract
Endogenous endophthalmitis (EE) is a rare but devastating infection that occurs secondary to seeding of the intraocular cavity from an extraocular focus. Recent reports suggest the increasing prevalence and incidence of Klebsiella pneumoniae as a causative organism in Asian countries. Analysis of the largest cohorts published to date suggests that K. pneumoniae endogenous endophthalmitis (KPEE) is 10 to 15 times more prevalent than other causes of EE. The incidence of KPEE among patients with systemic Klebsiella infection appears to be >100-fold more common than other causes of EE. The exact reason for these observations is not clear, but a number of studies now suggest that Klebsiella serotypes K1 and K2 have virulence factors that enhance their survival in diabetic patients and increase their pathogenicity. Here, we report two cases of KPEE in the USA. We also review the recent clinical and basic science literature on the prevalence, incidence, and pathophysiology of this emerging and devastating infection.

Abstract
PURPOSE Endogenous endophthalmitis secondary to Klebsiella pneumoniae liver abscess is a blinding infection that is being reported more frequently in the literature. The K1 capsule and magA contribute to virulence of systemic infection in mice; however, little is known about the role of magA in secondary ocular infections. METHODS To assess the role of K. pneumoniae capsule in endophthalmitis, the authors induced experimental endophthalmitis by direct inoculation of 100 colony-forming unit wild-type, magA-deficient, or magA-complemented K. pneumoniae into the posterior segments of mouse eyes. Eyes were analyzed by quantitation of viable bacteria, retinal function, and inflammatory cell influx as well as by histology. RESULTS Wild-type K1 K. pneumoniae caused significant ocular disease. At the end point of 24 hours postinfection, eyes infected with wild-type K. pneumoniae retained significantly less retinal A-wave function than eyes infected with an isogenic magA-mutant strain. B-wave function retention was also greater in eyes infected with the magA mutant than with wild-type K. pneumoniae. Additionally, intraocular growth of the magA-deficient strain was less than it was in the wild-type strain. The amount of myeloperoxidase elicited was also significantly higher for wild-type-infected eyes at 24 hours. CONCLUSIONS These results indicate that in the eye, the K1 capsule of invasive K. pneumoniae significantly contributes to the ability of the bacteria to disrupt retinal function, to grow to high density, and to persist despite immune cell recruitment.

Abstract
PURPOSE To report the first case of endogenous Klebsiella endophthalmitis associated with liver abscess in Iran. CASE REPORT A 79-year-old man was referred to our hospital due to severe pain and visual loss in the left eye. On physical examination, conjunctival hyperemia, corneal edema, hypopyon and severe vitreous cellular reaction were identified in the left eye; however, yellowish conjunctival discoloration was more apparent in the right eye. Abdominal CT scan showed a right liver lobe abscess that was confirmed by sonographically guided percutaneous liver mass biopsy. Blood, vitreous and liver mass aspirate cultures revealed Klebsiella pneumoniae growth. The patient was thus diagnosed with endogenous Klebsiella endophthalmitis secondary to bacteremia associated with liver abscess. CONCLUSION This report suggests that, rather than being confined to Taiwan, endogenous endophthalmitis secondary to a liver abscess due to K. pneumoniae may be a global problem. Therefore, physicians should be aware of the possibility of endophthalmitis whenever a patient with K. pneumoniae liver abscess complains of ocular symptoms.
